Hi Raj,

This scenario can happen only in case of parallel forking. I don't beleive that all the 2xx responces will reach the server at the same tume. If it so then i think the server will forward the 2xx response on some priority basis.

Subject: [Sip-implementors] Forking  INVITE SIP message - regarding

Hello,
   
  Consider the following situation.
   
              Adam wants to call Bob, let’s say that Bob is registered at three locations, that is, at home, at head office and at his branch office. Hence, when Adam makes a call, INVITE request is forked by the proxy and it reaches all the three destinations. Hence, three 200 OK SIP response will be sent back to Adam. 
   
              Consider the situation, when Bob’s friends answer the call at all the three locations at the same time, what will happen? Either three media channel will be established between them or which two will be discarded.
   
              Can anyone please clear this?
   
  With regards
  Raj.
